Preparedness & Response
Tracking Network data can be used to prepare for and respond to natural disasters or other public health emergencies.
We Track That
Knowledge of a community’s local infrastructure, vulnerabilities, and resources enables public health professionals to quickly establish priorities and take proper actions during emergency or disaster response. The Tracking Network datasets listed below can be used to
- identify community-specific threats and hazards, at-risk populations, and community vulnerabilities.
- make informed decisions about resources needed for public health response or public safety.
- determine potential public health actions that could lessen or prevent illness, injury, and death.
- evaluate possible scenarios based on time, place, and conditions.
Types of Data
The Tracking Network presents data in customizable maps, charts, and tables. Map layers can provide important contextual information including overlays of real-time data (weather radar, surface smoke, and active Atlantic cyclones) and points of interest such as day care centers and public schools, fire stations, hospitals, mobile home parks, National Shelter System Facilities, nursing homes, power plants, and urgent care facilities.
It is important to note that the following data are based on total populations, rather than individual members of a particular population.
This indicator includes population estimates (number and percent) of people by race, ethnicity, age, gender, single-parent households, speaking English less than “very well”, and aged 65 years and older and living alone. Data are presented at census tract, county, and/or state level for all states.
This indicator includes data on several health conditions that could make a person more vulnerable in emergency or disaster situations. Examples include certain disabilities, chronic health issues (e.g., arthritis, diabetes, high blood pressure), mental health issues, and overall physical health. These data are available at the census tract level for all 50 states. Sources include the American Community Surveyexternal icon, National Diabetes Surveillance System, and CDC’s Population Level Analysis and Community Estimates (PLACES) Project.
This indicator includes measures that may make people at greater risk for heat-related health effects. These measures are diabetes, heart disease, poverty, race, advanced age, social isolation, disabilities, population density, forest canopy, developed land use, and cultivated crop land use.
This indicator provides information about the housing units within a community. It includes the total number of housing units, as well as the number and percent of housing units with 10 or more units, more people than rooms, and no vehicle available. In addition, you can find the number and percent of vacant housing units, renter-occupied housing, and mobile homes. Also included are data on the number and percent of the population living in group quarters. Census tract-, county-, and state-level data are available.
This indicator provides information about internet access. It includes number and percent of people with access to computer with internet (but no cell phone). It also includes the number and percent of households with smartphones, households with a smartphone but no other device, and households with no internet access. In addition, you can find the number and percent of people who have a computer without an internet subscription, with different age, income, and education options. Census tract-, county-, and state-level data are available.
This indicator provides census tract-, county-, and state-level data on the percent of land used for agriculture and percent of developed land use. It also provides rural-urban county classifications.
This indicator provides county-level data on the numbers of hospitals, numbers of hospital beds, percentage of hospitals located within a flood hazard area, and percentage of hospital beds located within a flood hazard area. These data can be used to identify community vulnerabilities, plan resource needs, and inform disaster preparedness efforts.
This indicator shows relative vulnerability of every U.S. census tract on 14 social factors including poverty, lack of vehicle access, and crowded housing. The factors are grouped into four related themes. Each census tract receives a ranking for each variable, each theme, and an overall ranking. These data can be used by public health officials and local planners to better prepare communities to respond to emergency events like severe weather, floods, disease outbreaks, or chemical exposure. Depending on the year, data are available at the census tract and county level for all states.
This indicator includes data on poverty, household income, employment status, and high school (or equivalent) graduation status. Data are presented at census tract, county, and/or state level for all states.
This indicator provides county-level estimates on the total area and percentage of total areas within a flood hazard zone, as well as the number of residents and housing units per county in a 100-year flood zone. The data use flood hazard risk areas defined by the Federal Emergency Management Agency (FEMA) and the Environmental Protection Agency (EPA).
This indicator displays locations of predicted surface smoke concentrations from wildfires that are layered on top of county- and census tract-level measures of access to care and social vulnerability, health status, annual air quality levels, or population characteristics.
